     Want to compare 2 same-size bitmaps for equality? Want to compare 2 arrays for equality (even if arrays are different VarTypes)? NT-based systems have RTLCompareMemory, C has MemCmp. Win9x is reduced to byte by byte loops, more or less. This twist on that loop process comes really close to matching the speed of the two aforementioned API functions and can be used in every O/S. Thought I could use this for a project of mine, but the requirement went away. Compile the project for true tests (IDE is always slower). As always, stuffed with lots of comments.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
